Claims
- 1. A process for augmenting or enhancing the aroma of a perfume or cologne composition comprising the step of adding to a perfume or cologne base an aroma augmenting or enhancing quantity of a product containing a mixture of methyl substituted norbornane carboxyaldehydes having the structures: ##STR75## wherein R.sub.2 is methyl produced according to the process which consists of the step of admixing a mixture of methyl cyclopentadienes having the structures: ##STR76## with an alpha, beta unsaturated aldehyde defined according to the structure: ##STR77## wherein R.sub.2 is methyl in the presence of a catalyst having the structure:
- R.sub.m 'AlX.sub.n
- wherein R' is C.sub.1 -C.sub.3 alkyl and X is chloro or bromo with m+n=3 and m being 1 or 2 and n being 1 or 2; the reaction taking place at a temperature of between 0.degree. C. and 50.degree. C.; the reaction taking place in the presence of an inert solvent and in the presence of triethanolamine.
- 2. A process for augmenting or enhancing the aroma of a perfume composition or a cologne composition comprising the step of adding to a perfume base or a cologne base an aroma augmenting or enhancing quantity of a mixture of methyl substituted norbornane carboxyaldehydes having the structures: ##STR78## produced according to the process consisting of the steps of (i) intimately admixing a mixture of methyl cyclopentadienes having the structures: ##STR79## with an alpha, beta unsaturated aldehyde defined according to the structure: ##STR80## wherein R.sub.2 is methyl or hydrogen in the presence of a catalyst having the structure:
- R.sub.m 'AlX.sub.n
- wherein R' is C.sub.1 -C.sub.3 alkyl and X is chloro or bromo with m+n=3 and m being 1 or 2 and n being 1 or 2; the temperature of reaction being between 0.degree. C. and 50.degree. C.; the reaction taking place in the presence of a solvent; the reaction taking place in the presence of a triethanolamine promoter and (ii) reacting hydrogen with the resulting reaction product at a pressure of between 25 psig and 100 psig and at a temperature of between about 15.degree. C. and about 50.degree. C. in the presence of a catalyst selected from the group consisting of Raney Nickel and supported palladium.
